Reloading sections, open proxy, and context observer (SwiftLint)

This release fixes a few bugs with reload items and adds a method to reload entire sections.

The CollectionViewProxy internals have also been exposed to allow for custom use to update a collection view. This lands well with the new ContextObserver class which can be used to observe changes in a managed object context and handle them as needed.
